Against the decaying skyline here, a one-of-a-kind engineering project is
rising near the remains of the worlds worst civilian nuclear disaster.

An army of workers, shielded from radiation by thick concrete slabs, is
constructing a huge arch, sheathed in acres of gleaming stainless steel and
vast enough to cover the Statue of Liberty. The structure is so otherworldly
it looks like it could have been dropped by aliens onto this Soviet-era
industrial landscape.

If all goes as planned, by 2017 the 32,000-ton arch will be delicately pushed
on Teflon pads to cover the ramshackle shelter that was built to entomb the
radioactive remains of the reactor that exploded and burned here in April
1986. When its ends are closed, it will be able to contain any radioactive
dust should the aging shelter collapse.

By all but eliminating the risk of additional atmospheric contamination,
the arch will remove the lingering threat of even a limited reprise of those
nightmarish days 28 years ago, when radioactive fallout poisoned the flatlands
for miles around and turned villages into ghost towns, filled with the echoes
of abandoned lives.
